INSPECTION
As soon as a coil is received, it should be checked to insure it is still
under pressure per Figure 3. The coil should be inspected for possible
damage during transit. If damage is evident, the extent of the damage
should be noted on the carrier’s freight bill. A separate request for
inspection by the carrier’s agent should be made in writing. The Local
Distributor should be consulted for more information. The drain pan
should be checked for cracks or breakage. Before installation, the unit
should be checked for screws or bolts which may have loosened in
transit. There are no internal shipping or spacer brackets that need to
be removed.
It should be verified that all accessories such as heater kits are
available. Installation of these accessories or field conversion of the unit
should be accomplished before setting the unit in place or connecting
any wiring, duct work or piping.
